CVE-2026-26946
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.3.0.0, contains an improper privilege management vulnerability in the OS. A high privileged attacker with local access could potentially exploit this vulnerability, leading to elevation of privileges.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an improper privilege management vulnerability in the operating system of Dell ECS and ObjectScale storage platforms. A high-privileged attacker with local access to the system could potentially exploit this vulnerability to elevate their privileges further, likely by manipulating OS-level permissions or user account settings.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Dell storage productRun command to determine if Dell Elastic Cloud Storage or Dell ObjectScale is installed on the system (e.g., check for product-specific processes, services, or installed packages)Affected if The system is running either Dell ECS or Dell ObjectScale storage platforms
-
Determine the installed product versionUse product-specific command or configuration file to retrieve the exact version number of Dell ECS or ObjectScale (consult Dell documentation for version check commands)Affected if The exact version cannot be determined or the product is unversioned
-
Compare version against affected rangesCheck if the installed version falls within: ECS 3.8.1.0 through 4.2.x (anything less than 4.3.0.0 but >= 3.8.1.0), or ObjectScale any version below 4.3.0.0Affected if Installed version is within the affected ranges: ECS >= 3.8.1.0 and < 4.3.0.0, or ObjectScale < 4.3.0.0
-
Verify presence of high-privileged local accountsList local user accounts with elevated privileges (administrator, root, or product-specific admin accounts) that exist on the systemAffected if High-privileged local user accounts are present on the system
The system is affected if it runs Dell ECS version 3.8.1.0 through 4.2.x or any ObjectScale version below 4.3.0.0, and has high-privileged local user accounts that could be manipulated for privilege elevation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.3.0.0
